Whole ground floor rebuilds in Northwood
When a whole ground floor is rebuilt, the old slab or tired screed comes out, a membrane and insulation go down, and a new screed is laid over the top. On a big detached house that is several rooms, hallways and often a utility or boot room, each with its own threshold to meet. Mixing on site and laying by hand lets each of those Northwood rooms be finished to its own level.
The depth follows the build. Over insulation, a house floor goes in at 65mm, while commercial space takes 75mm. A bonded screed, fixed directly to a sound slab, runs from 25 to 40mm, useful when there is no room for anything thicker. Our screed depth guide sets out each figure in full.
For 2026, UK pricing puts a sand and cement floor somewhere from £18 to £25 per m². Adding fibres, which help control cracking, costs about £1 to £3 per m² more. Where a floor must dry faster, a quick drying mix shortens the wait.
Hillingdon's older homes are mostly twentieth century rather than Victorian. Just 4% of the borough's housing predates 1919; the semis of Ruislip, Ickenham, Eastcote and Hillingdon itself mostly come from between the wars and just after. Those houses often have original concrete floors that have cracked over time, and when one is past saving, sand and cement is a sound choice for the replacement, compacted and finished to a level base for any covering.
Wet rooms and garage floors in Hillingdon houses
Some rooms need cement. Shower floors you walk straight onto, and full wet rooms, slope down to a drain, and that slope is simple to form when the mix is laid by hand. Since calcium sulphate cannot be left sitting damp, these rooms get cement as a matter of course.
Garage conversions are another job suited to a site mix. The old garage slab usually slopes towards the door and sits below the house floor. We put down insulation and a membrane, then build the screed up until the converted room sits flush with the hallway. Each layer is explained in our guide to garage conversion floors.
Of Hillingdon's homes, 20% are terraced. In a terraced house there may be no parking outside and no side access, and a sand and cement screed can be barrowed through the front door without a pump waiting on the street.
The price you pay is the wait. Allow a day for each of the first 40 millimetres and longer for every one past that, so a 65mm floor can leave the tiler waiting weeks. Where the existing Ickenham slab is firm and only out of true, a coat of levelling compound could save you the rebuild. Towards the east, there is a sand and cement page for Ealing as well.
